Never give up on what you really want to do. The person with big dreams is more powerful than one with all the facts.

I must be willing to give up what I am in order to become what I will be.

I know quite certainly that I myself have no special talent; curiosity, obsession and dogged endurance, combined with self-criticism, have brought me to my ideas.

You never fail until you stop trying.

God is subtle but he is not malicious.

I have no special talents. I am only passionately curious.
